THE wit-nerds or, nonn- VEHICLES "A lication flied September 9, 1929, Serial No. 391,f20,1and, in GreatBritain March 25, 192 a v This invention relates 'to non-skid devices for the wheels of road-vehicles of thekind comprising a. number of chains or flexible members arrangeo across the tread of. the tyres. In connection with thistype of non-' skid deviceconsiderable diflicultyhas been experienced; in producing a construction havingv areasonable length oth'ie mfost of the constructions hitherto em l'o edshowin excessive wear after only a relatively short period of vuse. Furthermore m the known constructions, even whererollerswere employed as wearing'pi'eces the wearing pieces boreon 'the tyre and so wore the latter unf duly.

' "Referring to thedrawings The primary object of the presentiinvention is to construct a non-skid device which will be effective in use and relatively cheap to produce and which willhave a longer life than those hitherto commonly employed, and which; in addition'will notunduly wear, the 'tyre over whi h itis placed.

Fi -tire 1 is asi leview of a 'wheelwith-a' -"*-i1on-s ea device constructed according to one form of this'invention applied thereto.

Figure 8'i's a fragmental plan of the same. Figure 4 is a fragmentalsectional elevation of the same.

Figure 5 is a part sectional elevation of a modified construction of non-skid device constructed according to this invention.

Figure 6 is a plan of a part of a further modified construction of non-skid device according to this invention.

Figure 1 is drawn to a smaller scale than the remainder of the figures.

Referring to Figures 1 to 4 of the draw, ings l is the wheel, 2 are chains adapted to be annularly arranged around the rim of the wheel, one on each side thereof and 3 7 are transverse chains secured at each of the opposite ends 4 to one of the annular chains 2. The chains 3 extend across the wheel transversely of the main plane thereof.

Each of the transverse chains 3 comprises a number of l nks 5, between the inner ends of 'the'linkfi by this means a t v v The ends of the link {6 and particularly Eff which is neared a link-'6. :rh'e 11m; 6' sea v erably of plate formfof suitable thickness and is'provided with' -a pair of openings? The link 6 thus constitutes a pairofadja' cent closed loops and thelinkis provided with an eye 8 ateach' endby which the links; 5 are COHIIBGtQCltO it. flAn' integral arm extendsfromione end of the link 6 and may Oren-e of the eyes 8, and this integral arm conveniently fornran extension orja portion;-
